The Blair Building is an Art Moderne office building located in Decatur, Georgia. Built in 1939 by the Farnell Blair Company, the company used the second floor for its offices.

In 1946, Guy Rutland Sr. purchased the building to use as the headquarters for his trucking company, real estate business, and farm operations. Rutland served in the state legislature from 1953 to 1964. The building stayed in the Rutland family until 1994.

It was listed on the National Register of Historic Buildings in 2002.
